You basically have 3 types of Hysol ( out of the many references available from Loctite ) that are suitable for our hobby:
9462
E-20NS
E-20HP

9462 is a high impact high tear epoxy. It remains slightly flexible when fully cured. It is a great epoxy but takes about 2 hours to set and 15 to 24 hours to get fully cured. Coulor: cream.
E-20NS is my favourite. It is fast ( 20 minutes to set / 2 to 4 hours full cure ) and non sag ( very thick ). It has a very high shear force but get very hard, thus more breakable then 9264 when fully cure. Coulor: white.
E-20HP is the repair glue per excellence. It is fast ( 20 min/2-4 hours ) and fluid. That means that it is perfect to push into cracks. It is also very well suited to glue control horns into slots. Colour: transparent.

The 50 ml cans are best suited for our hobby. The type of tip matters as well.
For the best glue mixing, far reach and big work, I use long tips.
For small works, I use shorter tips ( quicker tip cleaning time, less glue waste as well )
For tip cleaning, I remove the inner spiral, clean with acetone and a brush ( thin brush fr the inside ). Let it dry before reassembling. Can be re-used 6 to 10 times. After a while the inner spiral will brake...

As a summary, I use 9462 for formers gluing in a fuselage mostly. Is use E-NS for almost everything else and E-20HP for repairs and control horn gluing.

Here is a very professional online shop that sells them ( as well as Mc Master Carr )
